  1. Yet another possibility for Fermi's Paradox

    That is what I thought. Intelligent aliens have nothing to gain by being detected. So they may use a cloak of invisibility through advanced technology to avoid being detected by equal or more advanced aliens. And in the event they came to Earth, they would be capable of removing any undeniable evidence of their presence here using their superior technology. But why would they have lights on the OUTSIDE of their flying saucers?
  2. Reputation Points

    How are these tallied? By wisdom? Complaints? By lack of cussing? For not being too obnoxious? Education? What else?
  3. Yet another possibility for Fermi's Paradox

    Could you please explain what the Fermi Paradox has to do with religion? I don't yet see the connection. In my mind the Fermi Paradox is explained by the possibility that interstellar travel is much more difficult than we think, and intelligent life is scarcer than we think. "...The second aspect of the Fermi paradox is the argument of probability: given intelligent life's ability to overcome scarcity, and its tendency to colonize new habitats, it seems possible that at least some civilizations would be technologically advanced, seek out new resources in space, and colonize their own star system and, subsequently, surrounding star systems. Since there is no significant evidence on Earth, or elsewhere in the known universe of other intelligent life after 13.8 billion years of the universe's history, there is a conflict requiring a resolution. Some examples of possible resolutions are that intelligent life is rarer than we think, that our assumptions about the general development or behavior of intelligent species are flawed, or, more radically, that our current scientific understanding of the nature of the universe itself is quite incomplete." https://en.wikipedia.org/wiki/Fermi_paradox I don't believe there is a paradox.
  4. Trump's latest tweet. What do you think? "Lightweight Senator Kirsten Gillibrand, a total flunky for Chuck Schumer and someone who would come to my office "begging" for campaign contributions not so long ago (and would do anything for them), is now in the ring fighting against Trump. Very disloyal to Bill & Crooked-USED!" Please help me figure this out. Because Gillibrand called for Trump to resign, so he lashes back with fury, that she is a "lightweight, flunky, would come begging for contributions, and would do anything for them." Even for Trump this is an outrageous, sexist slur, to the extreme. Then press secretary Sanders explains it away that if we think there is a disgusting sexual innuendo, it means our minds are in the gutter. What does Trump mean by: "Very disloyal to Bill & Crooked-USED!" Trump needs to be impeached, this is an insane thing to say and points to what I believe is a uniquely Trumpian dementia. It will only get worse with age.
  5. The center of galaxies, and along the spiral arms, have more heavy elements than the outer and less dense regions because there are more giant stars packed closer together near the center of the galaxy that go supernova and scatter their heavy elements around. Earth is in the galactic habitable zone because it is far enough away from the center of the galaxy with the deadly radiation but still close enough to populated regions to get enough heavy elements from supernovas.
  6. The North Korea Problem

    Can the US develop an anti-ICBM missile system that is 100% effective and so numerous that it can overwhelm any number of attacking missiles? Is it just a matter of time before anti-ICBM technology can actually make ICBMs obsolete? Can we park a few satellites in orbit over North Korea, and whenever they launch an ICBM, this defense system can destroy any ICBMs launched using lasers or particle beams or anti-missiles?
  7. Dark Matter or Dark Force

    The "unknown force" is gravity. Stop using the name "Dark Matter"? Motion of stars around a galaxy is caused by gravity alone. Galaxies follow paths because of gravity alone. Superclusters are drifting apart because dark energy is able to overcome gravity. Yes, there is a dark force, it is called gravity. Now please try to explain your theory in plain English that a novice as myself will understand.
  8. Space is not expanding here. It only expands between superclusters, where dark energy overcomes gravity. If viewing of distant images was rendered impossible, then obviously we could not see with the precision we do. Since we can see with clarity to the edge of the observable universe, even the structure of newborn galaxies over 13 billion years old. That means such blurring is not happening.
  9. Superclusters do not become more massive in the future. Their mass remains constant, only the matter within them gets rearranged. Yes, they won't ever be massive enough to impact other superclusters. However I think the mass of a supercluster will slow down expansion between adjacent superclusters. If there was no supercluster, and a void instead, the neighboring superclusters would expand away from each other faster. Is that correct StringJunky?
  10. Whatever happens with galaxy mergers within the Local Group, or even the entire Virgo Supercluster, will have no impact on the rest of the universe because all superclusters are isolated from all others.
  11. Will all of the galaxies in the Virgo Supercluster eventually become one giant galaxy? That is with the exception of a few galaxies that get ejected or torn apart during the mergers? "In roughly 150 billion years from now, the remaining galaxies of the Local Group will coalesce into [one] object, that being the next evolutionary stage of the local group of galaxies." https://en.wikipedia.org/wiki/Andromeda–Milky_Way_collision
  12. Age and shape of the Universe

    How can time begin some period after the BB, if our region of the Universe came into existence as BB occurred? Don't you think time would start when the BB banged?
  13. Media's "Made-Up" Stories About Trump

    According to Trump leaks are fake news because the sources are anonymous. So how can we be sure that, for example, the leak that Tillerson called Trump a moron, was not made up? Tillerson would not deny it, but theoretically how do we know most leaks are true since there is no way to verify them? Maybe that is why 46% of voters think some stories are made-up.
  14. Since the recent poll shows that 46% of all voters believe the media makes-up stories about Trump. Here is where the nearly one half of all voters may post what recent stories about Trump are (sometimes) made-up. Let's hear all about it. The media should not be allowed to get away with "made-up" stories about Trump. Any made-up stories folks? I think these 46% are NOT usually thinking about any specific news story as made-up, but rather a general belief: "Yeah I guess some of the stories are made-up" but only because Trump or his supporters make claims of fake news. Just voicing it or writing it, is enough to sew the seeds of doubt in anyone's mind.
  15. Trump Effects

    Russia. "During a meeting with members of the Senate Finance Committee at the White House Wednesday morning, he again denied the account [about his phone call to Mrs. Johnson]. "Didn't say what that congresswoman said," Mr. Trump said. "Didn't say it at all. She knows it, and she now is not saying it. I did not say what she said." Mr. Trump said he had a "lovely" conversation with the widow, but declined to say what "proof" he had of the conversation. https://www.cbsnews.com/news/trump-told-la-david-johnson-widow-that-he-knew-what-he-was-getting-into-congresswoman-says/ Interesting how Trump's denial could not use the personal pronoun "I". That sounds so much like a child lying. "Didn't say that...." and "Didn't say it at all." When a normal adult is HONESTLY and emphatically denying something they would more likely use the personal pronoun "I" in the initial denial, for emphasis. Just saying "didn't do it" is a way to rationalize what he said. I do believe his intention was to console the widow, but his "wise-guy" manner of speaking in fragments sounds too gangster. That is out of his control. He just does NOT have a way with words. Also Trump should know that it is very likely that the widow did not vote for him, statistically speaking. When chief of staff Kelly described the situation, he did NOT deny Trump said "he knew what he signed up for, but I guess it hurt anyhow...." but made it sound ok to say that.
